Definitions

  • This invention relates to self-cleaning, adjustable fluid nozzles, especially fluid valves having atomization capability.
  • Atomizer fluid valves having self-cleaning capability are well known in the art. Such fluid atomizer or mist valves are made, for example, in the USA by Spraying Systems Co. (Model No. 11005).
  • such fluid nozzles generally speaking, comprise an elongated nozzle body 200 having an exit orifice 202, a needle valve 204 coaxially mounted therein and normally biased against a spring means 206 so that its outlet end is just inward (upstream) of the nozzle exit orifice 202.
  • the nozzle body 200 is connected to fluid source, e.g. water, and is also connected to an air supply.
  • a cap member 220 having a mixing chamber 222 is retained at the end of nozzle body 200 by an internally threaded, knurled, nut 225.
  • the needle valve outlet position is coaxially adjustable from the rear end of the fluid nozzle by pin 210, in relation to the nozzle exit orifice 202, and such adjustment affects the atomization pattern and rate of liquid flow.
  • this type of fluid nozzle is self-cleaning, by moving the needle valve 204, again from the rear, into the nozzle exit port 202 against the normal bias of the spring means 206.
  • the movement of the needle valve with relation to the nozzle exit port is performed by turning a rear-mounted pin element 210 (e.g., by means of a screwdriver element) which in turn axially moves the needle valve (against its spring-loading) closer, or further, to the nozzle exit end 202.
  • Prior art atomizer valves do not have any front cleaning and/or front adjustment capability. Such frontal adjustment and self cleaning is especially useful in fluid atomizer heads, or nozzles, intended for use by the general public.
  • a fluid atomizer or "air mist" nozzle or valve of this invention has an elongated nozzle body provided with a frontal exit port, a needle valve coaxially moveable therein and normally biased against a spring means so that its outlet end is just upstream of the nozzle exit port.
  • the nozzle body is connected to a source of both water and air, as in the prior art.
  • the needle valve outlet position is controlled, vis-a-vis the nozzle body exit port, from the front of the fluid nozzle by providing a frontal control means for moving the nozzle body with respect to a fixed-in-place needle valve.
  • the frontal control means is provided with both a rotatable and an axial motion and comprises preferably a control knob or ring threadably engaging the nozzle body near the frontal end thereof.
  • the control knob is, in turn, mounted within a fixed flange plate, having a rearwardly extending cylindrical bore, for slideable axial movement within said cylindrical bore.
  • control knob As the control knob is rotated, e.g. clockwise, the nozzle body is constrained for axial movement, in an incremental fashion, relative to the fixed needle valve. This movement is produced because of the threaded engagement of control knob to nozzle body, and because a second friction means is provided constraining movement of the control means to a linear, axial direction.
  • FIG. 1 is a fragmentary perspective view of the frontal section of the atomizer nozzle of the invention
  • FIG. 2 is a perspective view of the entire atomizer nozzle of the invention, as viewed in the direction of arrows 2--2 of FIG. 1;
  • FIG. 3 is a cross-sectional view taken along the line 3--3 of FIG. 2;
  • FIG. 4 is a partial cross-sectional view of a prior art atomizer nozzle
  • FIG. 5 is a fragmentary, partially cross-sectional view of the atomizer nozzle of FIG. 5 showing the attachment of outlet nozzle cap member.
  • the nozzle body 200 is fixed and the needle valve 204 is coaxially moved relative thereto by means of the axial movement of a slot-headed pin 210.
  • the needle valve tip 207 is moved closer or further to the nozzle exit orifice 202 of the nozzle body 200, and, in this manner, the fluid flow ratios to the chamber 222 are changed, and the effluent atomizer flow pattern is also changed.
  • the needle valve 204 may act as a self-cleaner by pushing the pin 210 downstream towards, and through, the nozzle exit orifice 202 (by exerting manual pressure on the pin 210 in the downstream direction).
  • the needle valve 200 is spring-loaded by conventional means 206 and will return to its normal bias inwardly of the nozzle exit orifice 202 after the rearward manual pressure on pin 210 is released.
  • the conventional atomizer valve just described, is modified to be a front-adjusting and front self-cleaning nozzle in the following manner.
  • the modifier atomizer nozzle 10 is best shown in FIGS. 2 and 3.
  • An elongated nozzle body 12 is provided, having affixed thereto a cone-shaped exit end cap portion 14.
  • the cap 14 is retained thereon by threaded retainer nut 46, as shown in the prior art drawings (FIGS. 4 and 5).
  • the end cap portion 14 defines an exit orifice 15.
  • the nozzle body 12 itself terminates in a nozzle exit orifice 16 (shown in dotted line).
  • the nozzle body 12 houses a coaxially extending needle valve 20.
  • the nozzle body 12 is connected to an air supply, via air hose 21, in a conventional manner.
  • the nozzle body 12 is also connected to a source of water, under pressure, via line 23, by conventional means.
  • the modified valve 10 of this invention is preferably intended to be mounted behind a wall 30 of a shower or bathtub.
  • the bathtub or shower wall may be made of a plastic or other suitable material.
  • the bathtub or shower wall 30 has an enlarged opening 31 formed therein through which is passed a cylindrical section 33 of a flange member 32 until the exterior flange plate 34 of flange member 32 abuts wall 30.
  • Cylindrical section 33 is provided with external threads 33a for locking engagement to wall 30, by means of bracket arm 54, as will be described.
  • a frontal positional control knob means 40 is mounted for slideable movement through the cylindrical bore 35 of the cylindrical section 33 of flange member 32, the control knob means 40 being also in threadable engagement with externally threaded portion 44 affixed to the nozzle body 12 and cap member 14, by means of an internally and externally threaded lock nut 46.
  • the lock nut 46 is frictionally engaged with, and held to, the cap member 14 and external threads 44 of the nozzle body 12 and therefore acts as an integral part of said nozzle body 12.
  • Pin 25 is fixed in place by means of a bracket 50, one arm 52 of which is clamped onto pin 25 and the other arm 54 of which fixes the bracket in place by means of threadable engagement to the externally threaded flange plate 32.
  • Pin 25 (which functioned as a clean-out pin in the prior art, by moving needle valve 20 forward or rearward when pin 25 is rotated by a screwdriver blade or the like) now firmly retains needle valve 20 in place.
  • Bracket arm 54 serves as a lock nut to lock flange plate 34 to wall 30 as well as to retain pin 25 firmly in place.
  • Bracket 50 also carries an integral block member 56, having a relatively large surface area, frictionally engaging transversely extending section 57 of the nozzle body 12. Block member 56 prevents nozzle body 12 from rotating as it is being moved by the control means 40, as will be further described.
  • Control knob member 40 is provided with a stop ring 60 at its inner end 62 to prevent disengagement of the control knob 40 outwardly from the wall 30.
  • the nozzle body 12 and retained cap 14 are spring-loaded by conventional means, such spring-loading of the nozzle body being indicated by arrows A--A in FIGS. 2 and 3.
  • needle valve 20 is fixed in place, inward axial movement of the nozzle body 12 decreases the distance between needle valve tip 17 and nozzle exit orifice 16 in a precise manner.
  • a clearance 70 is provided between flange plate 32 and knob control means 40 when the stop ring or stop member 60 abuts the inner end of flange plate 34.
